Microchip expands stand-alone real-time clock/calendar family

by donpedro

Microchip announces the expansion of its family of stand-alone real-time clock/calendars (RTCCs). The MCP7940N builds on the success of the MCP794XX family, and offers battery switchover and timestamp for accurate timekeeping, digital trimming for time-of-day calibration and 64 bytes of SRAM. The new RTCCs offer a lower-cost alternative to the existing MCP7941X devices, which feature 1Kbit of EEPROM memory and a 64-bit reprogrammable unique ID. The MCP7940N addresses the need to reduce cost in smart-energy applications, such as thermostats, power meters and commercial refrigeration; home-appliances such as stoves, dishwashers and microwave ovens; automotive dashboard controls and car radios; as well as in consumer-electronic products such as office equipment, irrigation controls and video systems.
In applications such as the storage of perishable goods, or monitoring of access to secure rooms, the MCP7940N RTCC helps to address system health, safety and security issues.
